Abstract
A retractable assembly for a sensor, which determines a physical and/or chemical, process variable in a process medium. The retractable assembly has a housing, in which a tubular holder for accommodating the sensor is arranged such that it can be moved linearly by a drive unit. At least one cascaded cylinder is provided for the linear shifting of the tubular holder, wherein the cascaded cylinder comprises at least two cylinders arranged one after the other in the direction of the stroke movement. Furthermore, the cascaded cylinder is, or the cascaded cylinders are, embodied and/or operable in such a manner that the sensor is movable into at least two different positions.
